If you are interested in solar lights, you shouldn’t miss this article.

What are solar lights?

Solar lights have become familiar and are increasingly widely used worldwide. You can easily find solar lights in the media and even in your living environment.

Solar Light (Solar Lamp). The structure of solar lights depends on the manufacturer but generally includes key components such as solar panels, controllers, solar LED lights, rechargeable batteries, and other devices. Solar lights operate based on the common principle of activating the lighting system to produce light without using the grid. Instead, they directly use the energy generated by solar panels through the conversion of sunlight into electrical energy.

Benefits of solar lights

Solar lights demonstrate remarkable convenience, cost-effectiveness, and impressive applications in practice. The benefits of this product make solar lights a leading and useful choice for users.

Notable benefits of solar lights include:

  • Operates entirely on solar energy, optimizing cost savings.
  • Applies modern technology, enabling automatic operation, turning off when it’s bright and illuminating when it’s dark. This eliminates the need for manual switching.
  • Functions solely through the connection between solar panels and LED lights, reducing the cost of wiring or excavation during installation.
  • Enhances safety for users and construction projects.
  • Maintenance and repair costs for solar lights are reasonable.
  • Independence from the grid makes solar lights suitable for all types of projects, even in remote areas and islands.
  • Solar lights can operate normally for 3-4 days during rainy, cloudy weather.
  • Manufactured with modern technology, ensuring high durability and longevity.

Comparing the lighting efficiency of solar lights and grid-powered lights

Many consumers question the practicality and benefits of solar lights compared to grid-powered lights. Both are lighting products, but when it comes to efficiency, practicality, cost, and other factors, solar lights and grid-powered lights have distinct differences.

  • Installation, construction, and maintenance costs

When comparing solar lights with grid-powered lights, the installation cost is a crucial factor that users are particularly concerned about. According to surveys, solar lights show higher economic efficiency, with lower installation, operation, maintenance, and repair costs compared to grid-powered lights.

The installation cost also depends on the scale of the project. For large-scale installations, using solar lights is a perfect cost-saving solution.

(Note: The data in the table is for reference purposes only)

According to the chart, the installation cost of solar lights is much lower than that of grid-powered lights.

  • Usage efficiency

Experimental studies show that solar lights have significantly higher operating efficiency compared to grid-powered lights.

The lifespan of solar lights is evaluated to be longer. Costs incurred during use, as well as issues related to malfunctions and equipment replacement, are considered stable and less problematic than those of grid-powered lights.

  • Energy source

While grid-powered lights use electricity from the national grid, solar lights utilize electricity converted from sunlight. This brings safety, cost savings, and modernity to solar lights.

BMoreover, solar lights operate independently of the grid, eliminating concerns about power outages or fluctuations. Solar lights can operate consistently for 3-4 days during rainy and cloudy periods without sunlight.

  • Safety and cost-effectiveness

In surveys comparing the use of solar lights and grid-powered lights, it is evident that solar lights do not require a cumbersome electrical wiring system, resulting in higher safety levels compared to grid-powered lights.

In terms of convenience, solar lights can be installed easily even in remote areas, mountains, or islands where the grid does not reach.

  • Durability and longevity

While conventional grid-powered light bulbs typically last about 2-5 years, LED bulbs of solar lights have a lifespan of up to 12-15 years. The components of solar lights are made from high-quality and durable materials, with a product lifespan ranging from 5-8 years. Solar panels have a lifespan of up to 25 years.

Additionally, the casing of solar lights is made from corrosion-resistant and electrostatically painted materials, making them resilient to corrosion and impact, and they can operate well in harsh weather conditions. Therefore, there is no need for frequent maintenance or replacement costs, unlike grid-powered lights, and the product lifespan is higher.

  • Better lighting performance

Estimated data suggests that solar lights have higher brightness compared to grid-powered lights. The power of solar lights ranges from 10-150W. The light and brightness intensity of solar lights are commonly applied in various projects such as traffic infrastructure, residential areas, gardens, street lights, and industrial areas.
